Are you lactose intolerant? Yes, or no?

Is this map fake? There is no way around %60-80 people in Turkey are lactose intolerant. I have never met a lactose intolerant guy in my life. My daily breakfast is basically oatmeal and raisins with milk. But I feel like sometimes yogurt upsets my stomach.

Many people are lactose intolerant without knowing. The glucose level blood test can ascertain if an individual is lactose persistent for sure.

I think it would be waste of time to actually try to find out if somebody has no issues with drinking milk.

Does everybody you know consume milk in significant quantities? Intestinal microbiota are also a factor besides production of lactase. The test helps to quantify a rise in glucose levels which is more specific information.

I'm the only one in my circle who drinks milk regularly.

Not sure, I did Paleo diet once when I was 14 and all my bloating went away super fast and I felt amazing, either gluten and/or lactose intolerant to some degree.

If you've had a dna test you can see if you carry genes that show you are lactose tolerant or lactose intolerant. Lactose intolerance can kick in at a later age so I don't think these studies are incorrect. As Milkaner said a lot of people don't realise they are lactose intolerant as they don't really drink much milk.

If you have done 23andMe for instance the gene below is the one you check. If you have one of two As you are lactose tolerant and if you have two Gs you are lactose intolerant. My result below showing two AAs so I'm lactose tolerant.

No, i'm not intolerant.

I am going to do Family Tree DNA's Family Ancestry Test. I don't know if the results will show that I am lactose intolerant or not. Maybe there is a way to find out with raw data.

The Greeks who settled in Australia were predominantly islanders, so their frequency of lactose persistence is likely even lower than Greece overall.

According to one study 44.7% of continental Greeks are lactose intolerant based on glucose levels after milk consumption and it was found more common among Cretans and Greek Cypriots although the samples were smaller. Probably most Greek Australians are lactose intolerant.

This later study found 75% of a sample 200 Greeks from across the country as lactose intolerant according to glucose levels with it rising up to up to 87% among the 47 Islanders

I can't find any data for rs4988235 or rs182549 associated with lactose persistence in Europeans for Greece but it should be well below the European average.

There's no way it's that high. Most people consume dairy products and don't face any problems. I myself am consuming dairy products everyday in big quantities and I have nothing. Same as almost everyone amongst my relatives.

I in particular don't have any problems. It only "eases" me up when I have constipation.

Edit: saw the survey based on which the results for Greece were drawn from: too little of a sample to judge properly. 200 individuals cannot judge tens of million Greeks.

Not all dairy products contain significant lactose. Do you ever drink milk in significant quantities?

You are right that the sampling might be too limited to be fully representative. What it does still likely indicate is that Greek Islanders might have higher rates of lactose intolerance than mainlanders. This should not be too surprising given the latter have a bit more Northern/Slavic admixture.
